It is mainly based around beans, rice, or other grains. I have had to cut a lot of corners from the days of working in restaurants. $20 is around how much I spend on a typical week...that is assuming that I have all of my pantry items fully stocked, such as seasonings, oils, etc.. Once all of that is taken care of, the rest is pretty simple. I don't tend to buy a lot of luxury items and I buy whatever produce is in season. Produce can be pretty inexpensive especially in California. When traveling, I notice fruit and veggies can be a bit more pricey. One of my keys to keeping costs down is planning my meals so that I don't have to grab a burrito somewhere while I am out and about. I make sure to make a pot of lentils and brown rice w/ veggies on a daily basis. I usually add onion, carrot, celery and spices to it and top it off with hot sauce when I am finished. That is one of my convienient foods. I have a hot plate in my studio, so when I am working on music, I have food cooking in the background constantly. I also try to have raw fruit and veggies on hand whenever possible.
